Significant differences were noted between grade 1 and grade 3 tumors as well as between grade 1 and grade 2 positive cancers with regard to SLC2A1 expression (p < 0.001 and p < 0.05, respectively), as well as between grade 3 and both grade 1 and 2 positive cancers with regard to SLC2A3 expression (p < 0.01 and p < 0.05, respectively). The gene discussed is SLC2A3; the disease is cancer.
